Comment policies

I intend to have as few rules as possible about comments on this blog. I may add new rules as the need arises.

  1. I will delete or not answer comments that consist largely of questions about homework. (Also, I do not answer homework questions sent to me by e-mail.
  2. I will delete or not answer requests for "image processing codes."
  3. I will delete product advertisements.

    Dont you think that is very selfish of you?Not that I have a problem with it,sometimes people need help just like you did before you knew anything about image processing.Be considerate!

    No, of course I don’t think I’m being selfish. I’m simply guarding my (finite) time, as well as the time of my readers. Based on what I’ve seen in other forums, if I answered any homework questions here, this blog would quickly devolve into a homework answering service. I’m not interested in that, and in my judgment it isn’t the best way for me to provide value to readers and to The MathWorks. I’ve had plenty of experience both as a teaching assistant and as a professor, but that’s no longer my job.

    Thanks for taking the time to leave a comment!
